Welcome To Timberline Longhorns
Located in Colleyville, Texas
Timberline Longhorns began as a father-son dream in Colleyville, Texas, when Grant Tinkis and his dad started their first herd. Nearly a decade later, the operation has grown and moved to Alvarado, TX, where the ranch now spans more land and more Longhorns than ever before.
We’re passionate about raising Texas Longhorns that combine eye-catching color, big bodies, and signature twisty horns. Our herd reflects years of learning, refining, and growing with purpose. Whether you’re building your own program or just want to visit, we’d love to connect—ranch tours and cattle conversations are always welcome.
